The 3D models help a lot to visualise what's going on inside these engines.

[@slicedbread9003]

An important development for Honda automotive engines was the CVCC engines or stratified charge engines. This allowed street cars to get excellent drivability with improved gas mileage and pass emissions tests. It worked so good that Honda thought that they would license it to other auto manufacturers. This worked absolutely great. I had a 1981 Honda Accord that had a CVCC engine. It was near perfect for it's time. Good gas mileage, excellent drivability and as reliable as a brick. Brilliant engineering.

[@RogerMiller-td5yc]

Yea in the begging of emmisions control, these engines passed with no catalytic converters, an amazing feat!

When Honda revealed the GX series of industrial engines, it almost immediately replaced the old, inline style single cylinder engines in go-karts. It was more compact, ran smoother and fitting much better to the constraints of a go-kart. Basically anything "mini" was powered by a GX or its clone derivative. I dabbled in them for a couple of years, hopping up a clone from 6.5HP to 13 HP. Until the clone crankshaft broke and I threw away basically everything below the head. But the fun thing about these engines is: you can source pretty much any part for them. You dont have to waste money on a clone engine and have a box full of parts you wont use. All you need is a fresh block, side cover, a genuine honda crankshaft, high quality main bearings and the cylinder head. Everything else is pretty much aftermarket hop up kits. And the only investment I highly recommend for your build is a genuine honda crankshaft. Its much much stronger than any cheap clone one. Everything else is basically how much you are willing to spend...

bit like the pit bikes. my first pit bike, ten minutes, wheels going all wonky. axle like a noodle. shoved some honda axles in, i was taking that thing of 10ft jumps... so then it was the swingarm shaft. ditto. honda. got an old side valve honda here i think is so old its simply a "G"... been a while since i looked.

[@1crazypj]

The GX motors had really weak pressed tin rocker arms that 'folded' at the pivot. I found main reason was that plant fitters using them on generators, pumps and other industrial equipment were trying to run old cast iron side valve type valve clearances (0.008" to 0.016") instead of almost zero valve clearance (I set them same as motorcycle valves, 0.002" to 0.003" as I had run motorcycle dealer workshops until I found industrial equipment paid far far better) There were 32 non running GX engines at the place I worked, (UK Plant) when managing director visited I was introduced as 'The Honda Expert'

I owned a 1971 Honda CB500-4 for several years. Not any sort of racing bike, redline was only (IIRC) 10,500, but in street trim with a cheap fairing it would still bust 90 mph and ran out of revolutions before it ran out of power. A longer front sprocket might have gotten the century. And when I rode it as a courier in downtown Seattle, I got 52 mpg day after day. I replaced it when the clutch started slipping and I couldn't afford to pay to get it fixed (I'm not motorcycle mechanic) -- but the CM400T I got wasn't at all the bike that four-banger had been. One fun thing, my CB500-4 was stolen once -- parked in the street in front of my apartment, I got up one day and it was gone. Police found it a couple days later, five blocks away at the bottom of a hill (pushed into a blackberry thicket). The thief had tried to hotwire it by cutting all the wires to the ignition switch and twisting them all together. When I got to the impound yard, I untwisted the wires, replaced the blown main fuse, traced which wire went to ground, and left that one out of the bundle when I twisted the wires back. Two kicks and the bike started; I rode it for two more years with a toggle switch for the ignition (and by that time, I also had replaced the diode pack for the 3-phase alternator with a pair of full wave bridge rectifiers from Radio Shack). If I ever get another bike, I hope I'll be able to find a Honda I can afford and enjoy...

[@romandybala]

Very good explanation of Honda technology. My motorbike riding in a serious way began in 1966 as a 14 year old riding a honda 90. I always appreciated their quality and simplicity of repair and maintenance. Owned quite a few and cannot remember any issues with them.

[@herseem]

I think the secret of the 'big bang' firing order was that it was to do with the psychodynamics of riding a bike. With even power, the smooth power delivery would be more likely to produce a 'cliff edge' loss of grip so, it could lose grip with no warning which made it very difficult for the rider to back off the throttle in time as everything happened too quickly. With a lumpy 'big bang' firing order, the power comes in pulses and the rider gets warning of when the bike is beginning to slide so they can back off in time in stead of the bike letting go before they've had time to react. This means the rider can keep the bike closer to the edge of its grip capability and therefore use more of the power available.

[@drmoose7233]

that makes sense

[@Hawk7886]

Nah, I don't buy it. Riding along the knife edge of traction is difficult, but far from impossible. Modern tech does slap a bandaid on the issue, though.

[@jasonadams2264]

nah sorry this makes no sense. The grip and the engine pulses are uncoupled. riders dont judge the edge of grip by the engine power pulses. that makes no sense. How many times the engine hits per tire revolution is different for every gear and gearing combination, and every tire size. Many parts of this video I take at face value, but this part smells like bull

[@herseem]

@@jasonadams2264 it absolutely does make sense because of striction. The coefficient of friction between most materials is higher when stationary compared to when already sliding. That's why you can get a 'cliff edge' loss of grip. Applying power in pulses means you start to get lots of micro losses of grip which gives you an early warning you are right on the edge. This is what energies you to back off the power - It's a feedback loop. Furthermore that exact same technique is used by some shunting engineers to be able to apply maximum pulling power without spinning their wheels

[@jasonadams2264]

Im still not buying it. Been riding and studying motorcycles for the vet 40 years, and I have just finished tony foales book „motorcycle handling and chassis design“ for the third time and not a single sentence implies engine firing order had fuck all to do with grip. If you can provide some actual scientific research for this, I am all ears. One cannot feel engine pulses through the back tire, they happen entirely too fast together to be physically aware of. Any idea how fast engine pulses happen at even 1000rpm? This doesn’t hold water.

You guys are both wrong.

[@_..-.._..-.._]

Only idiots who drive vehicles with direct injection and/or cylinder deactivation have those issues and it’s from not maintaining them on the DI side and Cylinder deactivation is almost always a bad idea. People buy cars based on looks and features instead of reliability. Toyota Direct Injection uses both port and direct injectors because they knew direct only would be terrible on intake valves and cylinder washing. People are buying garbage like Mitsubishis and Nissans because they look cool despite both companies being on the verge of collapse and making unreliable garbage.

[@artpatronforever]

Honda provided motorcycle drive chains protected by a case which also serves as a safety guard. This is a great feature useful to extend chain service life and extends the interval between needed chain slack adjustment. Especially when off road riding, the chain case prevents sand from quickly destroying chains and sprockets, reducing maintenance. If a motorcycle has a chain drive, a chain case is good to have, and Honda shows having that wisdom. Do others?

[@crpth1]

In fact that's a detail where others lead the way. Others being CZ, Jawa, MZ... (the 2 stroke king). Pretty much all of the so called Eastern brands. Inclusive many Western brands. Or in other words brands more concerned with durability than aesthetics. ;-)

[@artpatronforever]

@@crpth1 When you see motorcycle couriers in India you see chain cases on many high use motorcycles, usually see smaller displacement high fuel efficient engines also. If the bikes didn't come stock with the encased chains they would be an aftermarket part everybody would put top of their list to add what is missing.

The 3D animations are out of this world. Gargantuan amount of information here. Now, not to be nitpicking, but you saying that "central timing" is what is used nowadays sounds incorrect. Maybe my english isn't good enough. If you're talking about where the timing chain/gears are, those have been - on in-line 4 liquid cooled engine - located on the left side, not on the center, for many decades. Since in-line 4 liquid cooled engine is by and large the most common internal combustion configuration, both for cars and bikes, it seems to me you're talking about air cooled engines from the 70's. As for your mention about Yamaha's engine, I'll first need to check into the shop manual downstairs.

[@reinerressel975]

Good explanation , NO normal aspirated engine can beat a TWO Stroke engine !! Diesel or self ignition engines 25-30 hp/ L , gasoline 4 stroke engines max 260 hp/ L and 2 stroke ( actually 2 at the same time = 4 str.) more then 400 hp/ L !!! Kreidler 50 cc and 21 hp in 1970 year .

[@younan68000]

ホンダの問題は、高回転でエンジンの特性が急変し、コーナーで車の制御ができずに追突してしまうというのが、社会問題となった。 過給エンジンは、だいたいどこで踏んでも同じ様に瞬時に立ち上がるが、NA はそうは行かない。 低回転時は、アクセルにほとんど応答しないので、アクセルを開け気味になる。 運転しているとこの領域が99%なので、コーナーで高回転を使うといきなり立ち上がる。 バイクだけでなく四輪でも死亡事故率が高かった VTEC 問題があり、安全を優先するユーザーは過給を買っていた。 実際にアクセルあけてからの反応は、過給の方が圧倒的に良く常に一定の反応を楽しめるのに対し、VTEC は常にかったるさを我慢しなければならなかった。また事故が多い。 これではね。 いくら出力が出ても、ダメなんだよ。

Virtually all the GP engines these days are V4's. Hondas line of VFR motorcycles means Vee Four Racing. Only in 2010 did they up the displacement from the 700-750cc bikes they built to 1,237cc. Because of the high cost of the bike, few were sold, but it had frightening power of 170 HP and even with shaft drive had an actual 152HP at the rear tire. I own one of these and yes, it is frightening, much beyond my '94 Yamaha V-max. Most people that look at it don't know what it really is.

About GP500 cc, Yamaha had twice the wins from 1975 - 1995. If we take the span to 2000 they where even. So I doubt that the Honda Race Engines was outstanding. I know that much of the wins are depending on the driver but you must have a good motorcycle too.
